Transient CD15-positive endothelial phenotype in the human placenta correlates with physiological and pathological fetoplacental immaturity
2013
Abstract Objective Placental growth and villous maturation are critical parameters of placental function at the end of pregnancy. A failure in these processes leads to the development of placental dysfunction, as well as fetal and neonatal mortality and morbidity. The aim of the study was to determine the relevant diagnostic markers associated with pathological placental development. Study design Forty tissue samples from normal placentas of different gestational age and 68 pathological term placentas with defective villous maturation (GDM, idiopathic IUFD, preeclamsia, HELLP syndrome) comprised the comparative immunohistochemical study (CD15, CD45 and CD34). Positive immunohistochemical re…
Awareness of HPV infection and attitudes toward HPV vaccination among Latvian adolescents
2016
Objective\ud To evaluate awareness of HPV and its vaccine among Latvian adolescents.\ud \ud Methods\ud A cross‐sectional survey was conducted in a 2‐week period in September 2015 among 270 adolescents attending a secondary school in Riga, Latvia. All students present during sexual‐health classes (grades 10–12 [aged 16–21 years]) were included. A self‐administered paper‐based survey assessed sociodemographic factors, sexual behaviours, smear history and knowledge of sexually transmitted infections, HPV and HPV vaccine knowledge, and sources of information.\ud \ud Results\ud Overall, 121 surveys were completed (62 by male students and 59 by female students). Latvian adolescents lacked awarene…
Reproductive health problems in rural South African young women: risk behaviour and risk factors
2018
Background South African young women continue to be vulnerable, with high prevalence of teenage pregnancy, HIV, sexually transmitted infections (STIs) and female genital schistosomiasis (FGS). This study seeks to examine the underlying factors that may be associated with these four adverse reproductive health outcomes. Methods In a cross-sectional study of 1413 sexually active of young women, we explored these four adverse reproductive health outcomes by considering socio-demographic factors, socio-economic factors, sexual risk behaviour, substance abuse and knowledge about reproductive health by using a questionnaire. Consenting participants were asked about previous pregnancies and were t…
Risk factors for unwanted pregnancy and subsequent abortion among women aged 16 to 25 years in Latvia
2015
Objective To investigate the risk factors associated with unwanted pregnancy in 16- to 25-year-old women in Latvia. Methods Case-control study of 16- to 25-year-old, sexually active women who did not want to get pregnant: the cases were 144 women who underwent their fi rst abortion whereas 278 nulliparous women served as controls. Data concerning them were obtained by using a semi-structured anonymous questionnaire that included questions about education, sexual life habits, contraceptive practice and a multiple-choice test to assess knowledge about contraception. Results Women who underwent an abortion had had more lifetime sexual partners, had more often not used any contraception, and we…
Pituitary-adrenal responses to corticotropin-releasing factor in late onset 21-hydroxylase deficiency
1990
Intravenous corticotropin-releasing factor (CRF) and adrenocorticotropin hormone (ACTH) were administered in patients with adult onset 21-hydroxylase deficiency to compare their diagnostic capability as well as to investigate hypothalamic-pituitary-adrenal function in this disorder. Responses of 17-hydroxyprogesterone, which were markedly elevated compared with controls, were identical with CRF and ACTH. However, intravenous ACTH resulted in higher androstenedione levels in comparison to CRF. Adrenocorticotropin hormone also resulted in decreased cortisol responses, confirming a defect in steroidogenesis, a finding that was not evident with CRF. Plasma ACTH responses to CRF were similar in …
Ovine corticotropin-releasing factor and dexamethasone responses in hyperandrogenic women
1990
Eighteen hyperandrogenic, hirsute women received ovine corticotropin-releasing factor (CRF; 1 microgram/kg) as well as a dexamethasone (DEX) suppression test. Nine of the 18 hirsute women exhibited increased DEX sensitivity. Plasma adrenocorticotropic hormone (ACTH) responses after ovine CRF were significantly lower in the DEX-sensitive subgroup, but serum androstenedione was higher. Baseline serum androgen levels could not predict DEX responses. A significant negative correlation existed between the suppression of androgens after DEX and the increase in ACTH after ovine CRF. The suppression of androgen correlated with the ratio of the increase in androgen to the increase in ACTH after ovin…
Physiological Estrogen Replacement May Enhance the Effectiveness of the Gonadotropin-Releasing Hormone Agonist in the Treatment of Hirsutism
1994
GnRH agonists (GnRH-A) have been used for the treatment of hirsutism in women with ovarian hyperandrogenism. However, significant side-effects, including vasomotor symptoms and bone loss, have prevented the long term use of this therapy. In this study, we evaluated the effects of low dose (physiological) estrogen replacement on the side-effects and clinical and hormonal parameters of 22 hirsute women with ovarian hyperandrogenism when treated with a long-acting GnRH-A, Decapeptyl. Ten patients with Ferriman-Gallwey (FG) scores averaging 13.4 +/- 1.5 were randomly assigned to be treated with Decapeptyl alone (3.75 mg, im, every 28 days for 6 months), and 12 other patients with FG scores aver…
Stro-1/CD44 as putative human myometrial and fibroid stem cell markers
2015
Objective To identify and characterize myometrial/fibroid stem cells by specific stem cell markers in human myometrium, and to better understand the stem cell contribution in the development of uterine fibroids. Design Prospective, experimental human and animal study. Setting University research laboratory. Patient(s)/Animal(s) Women undergoing hysterectomy for treatment of symptomatic uterine fibroids and female NOD/SCID/IL-2Rγ null mice.

Laparoscopic sentinel node mapping with intracervical indocyanine green injection for endometrial cancer: the SENTIFAIL study – a multicentric analys…
2020
ObjectivesLaparoscopy is commonly used for endometrial cancer treatment, and sentinel lymph node (SLN) mapping has become the standard procedure for nodal assessment. Despite the standardization of the technique, there is no definitive data regarding its failure rate. The objective of this study is to identify factors associated with unsuccessful SLN mapping in endometrial cancer patients undergoing laparoscopic SLN mapping after intracervical indocyanine green (ICG) injection.MethodsWe retrospectively evaluated a consecutive series of endometrial cancer patients who underwent laparoscopic SLN mapping with intracervical ICG injection, in four oncological referral centers from January 2016 t…
Cumulative newborn rates increase with the total number of transferred embryos according to an analysis of 15,792 ovum donation cycles
2011
Objective To measure the success of in vitro fertilization (IVF) of donated ova according to cumulative newborn rates (CNBR) per number of embryos required to achieve at least one newborn (EmbR), considering in addition the relevance of age and infertility etiology. Design Survival curves and Kaplan-Meier methods were employed to analyze CNBR with respect to the number of EmbR in a retrospective cohort of oocyte donation recipients. Setting University-affiliated infertility center. Patient(s) Infertile couples undergoing IVF with oocyte donation. Intervention(s) None. Main Outcome Measure(s) CNBR per EmbR. Result(s) The CNBR increased radically (up to 64.8%) between 1 and 5 EmbR, moderately…
